Q2: What will happen if user will use 1,35V DDR3 in 1,5V system? Q1: What will happen if user will use 1,5V DDR3 in 1,35V system? Any digital chip power consumed is directly proportional to frequency and voltage squared. Voltage drop over the years is because of power saving. There are PC3 RAM modules that works on both voltages. DDR4 is marked PC4.ĭDR3 - PC3L works on 1,35V voltage. DDR3 is marked PC3 or PC3L (L - for low voltage). DDR2 is marked PC2 on physical memory stick/ module/ PCB. DDR is almost never found in working PCs. In our days (year 2019) DDR3 and DDR4 RAM modules are more widely used. They are not compatible with each other and can not be mixed. There is DDR, DDR2, DDR3 and DDR4 RAM standards.

And please, correct me if I am wrong.ĭDR full name is DDR SDRAM (Double Data Rate Synchronous Dynamic Random-Access Memory). Please, help me to finish all information about DDR3 RAM. Lets make everything clear about DDR RAM. Consumer CPUs are typically limited to two or four ranks per channel while server processors can often handle eight or more ranks this explains why many Intel Xeon processors can accept extremely large amount of memory (768 GB for Xeon E5 V3 parts). The highest density memory modules (32 GB or more) are intended for server use and generally will not work on consumer systems that use Intel Core processors. Dual-rank (2R) modules appear to the system as if two memory modules were inserted in that memory channel, which may cause compatibility issues if you have multiple such modules on the same channel.

Greater battery use than our stated values.ġR and 2R refer to the number of memory ranks on the module.

Damage to the CPU IMC (due to the increased potential difference).

New Haswell CPUs require this and using 1.5V memory can cause problems along the lines of: Please note we fit 1.35V memory into our G750s. Notebooks utilizing 4th Generation Intel (Haswell) processors require a new type of memory known as DDR3-Low Voltage or “DDR3L”. Notebooks Cannot Complete Power On Self Test (POST) When Used With DDR3 Memory Module Newer Intel processors (since fourth-generation Haswell) require DDR3L memory regular DDR3 modules are out of specification for these processors and can cause the system to fail:

PC3 is standard voltage (1.5 V) DDR3 memory, while PC3L is DDR3 L low-voltage (1.35 V) memory.

These modules aren't compatible with each other. But if it is only the 1Rx8 and 2Rx8 in concern, they may be compatible with each other but it's best to check the motherboard manufacturer's list of compatible RAMs. So in short 1Rx8 PC3L 12800S and 2Rx0S RAMs are not compatible with each other. So PC3 and PC3L RAMs are not compatible with each other. On the other hand using a PC3L RAM in a PC3 RAM slot may damage it due to overvoltage. So using PC3 RAM in a PC3L RAM slot will not provide it sufficient voltage and it will fail to operate. But you should go through the motherboard manufacturer's guide of supported RAM modules just to make sure if they are compatible or not.Ĭoming to the PC3 and PC3L part, PC3 RAMs requires an operating voltage of 1.5V whereas PC3L requires an operating voltage of 1.35V. Higher the number of banks, the fewer the chips in the memory module, the better the reliability and power consumption.Ĭompatibility is generally not an issue in most cases. The x8 in them specifies the number of banks in the memory module.

Rank is a data block which is 64 bits wide without Error Correction Code (ECC) created using some, or all of the memory chips on a module. 1Rx8 means it is a single-rank module and 2Rx8 means it is a dual-rank module module.
